I decided to get a rice cooker, as I had problems cooking rice. It either came out too sticky, or undercooked, rarely could I get it just right. With the rival rice cooker it comes out perfect almost every time. There are only a few problems with the cooker that I can tell, and this is why I rated it a seven total. First, it seems to take forever to cook rice, at least over an hour. When I cook it on the stove, it usually was done between forty to fifty minutes. Next, it seems this makes a little mess when cooking. If you fill it up to cook more rice, it seems to overflow with sticky rice water. I go by the directions, and it still overfills. I think the designers could have made it a little bigger so it didn't do this. Performance Cooks rice almost perfect every time. Ease of Cleaning Really easy to clean. The only problem is that when it boils over, it leaves a sticky mess on the sides of the rice cooker. Ease of Use Really easy to use, you just fill it up to the lines and put the rice in. Anyone could cook with it that can read the directions. Durability Very durable, as I've owned this rice cooker for well over a year now. Design The designers need to do something about the fact some of the water boils over when cooking large batches of rice. I go by the directions exactly and it still overflows. If it wasn't for this it would be almost perfect. Even with this drawback I would still rather use it than cooking on the stove, as it cooks rice almost perfect.
